Method Detail

sleep

public boolean sleep()

This method puts the UI thread to sleep until a event to dispatch is received or it is awakened.

Returns:

true if an event to dispatch was received, false otherwise.

invokeAsynchron

public void invokeAsynchron(Runnable task)

This method invokes the given task asynchronous in the dispatcher thread of the UI. The term "asynchronous" means that this method may return before the task is invoked. If there is NO dispatcher thread in the underlying UI implementation, the task may simply be invoked directly in the implementation of this method.

Parameters:

task - is the job to invoke.

invokeTimer

public void invokeTimer(Callable<Boolean> task,
                        int delayMilliseconds)

This method invokes the given task periodically. The first invocation is performed after the given delay. Every time the task returns true, another invocation is performed after the same delay until false is returned.

Parameters:

task - is the job to invoke.

delayMilliseconds - is the periodically delay in milliseconds when the task shall be executed.

invokeTimer

public void invokeTimer(Runnable task,
                        int delayMilliseconds)

This method invokes the given task asynchronous after the given dalay.

Parameters:

task - is the job to invoke.

delayMilliseconds - is the delay in milliseconds when the task shall be executed.
